ABSTRACT In this article the quasi-modes model is used to observe the
influence, in electromagnetic transient phenomena, of considering a more
accurate representation of soil, taking into account the earth
conductivity and permittivity frequency dependence. For an actual 440 kV
three-phase transmission line the soil behavior is represented through a
unique real value of conductance and through a more accurate model,
considering its electromagnetic behavior
